Corrected entry: When Luthor is showing Lois maps of the new continent he intends to create, the final map initially shows a large 'state' marked out in the centre of the star-shaped island, with several other territories making up the points of the star. The shot changes as Luthor heads above deck, and we see the map behind him, but now the borders of the territories have changed and the central state takes up less space.

Correction:If you watch the scene, this "final" map you refer to is the 2nd to last map. This is where you see the so-called central state and surrounding territories. However in this map the west coast states and Mexico are still visible. In the actual final map, nearly all of the US, Canada, and Mexico is gone and in it's place is a now even bigger new continent. However, since this final map is now a wider shot of the whole Earth, it appears smaller. It is this image of the new continent on the actual final map that the camera zooms in on as Luthor goes above deck.

Corrected entry: Originally conceived as the start of a brand-new Superman franchise, it was reworked as a semi-continuation of the previous series, as a tribute to Christopher Reeve after he became paralyzed.

Correction:Unlikely. The accident that paralyzed Reeve occurred eleven years before this movie's release. If, however, this is stated on the DVD's Director's commentary then resubmit it with that information, as it would provide verification of this statement.

Corrected entry: On Lex Luthor's Russian-made missile launcher, the second button from the left is labelled "otkaz", which is presumably intended to mean "abort". The correct word would be "otmena". While "otkaz" is a general synonym, in a technological context it means, rather unfortunately, "equipment failure".

Correction:It must be the panel reset in the event of an equipment failure, rather than the abort button. We have such resets on all the machinery I work with.

Corrected entry: When Jor-El is "talking to" Lex, footage of Brando is used from Superman I in which (in this movie) he says "So. Kal-El. Speak". However, in the first film the line was "So. Speak", to which Clark asked who he was and was then told his Kryptonian name.

Correction:So, what's the mistake that you're claiming? Yes, they've manipulated old footage for the new film, that's true, but this isn't a video that repeats the same every time; it's an interactive projection of Jor-El created by Kryptonian technology. This isn't the same incident as the original Superman film; it's a different situation, ergo, the projection doesn't have to say the same thing.

Corrected entry: As Superman is shown flying literally 3 feet or so above the surface of the ocean, the water is not affected at all. It was established in the beginning of the scene that he was exceeding the speed of sound, and anything flying at that speed that close to the surface of the water would produce a wave/rooster tail of at least 20 feet or so.

Correction:He is flying significantly higher than three feet and his speed is never established; there is no sonic boom so we must assume he is not traveling the speed of sound.

Corrected entry: When the bank-robber with the Gatling gun shoots Superman in the eye from close range with his pistol, the bullet flattens and deforms upon impact with Superman's eye, and then falls lazily to the ground directly at their feet. The bad guy even watches as the bullet falls. This shouldn't happen: The bullet should have ricocheted off of Superman's eye with a lot of latent energy since none of it was dissipated upon impact. The bullet would have violently ricocheted away from the area just like the hundreds of bullets fired at Superman from the machine gun did. Also there is no way that any human could react fast enough to actually watch a ricocheting bullet from that short distance.

Correction:From Wikipedia: "The likelihood of ricochet is dependent on many factors, including bullet shape, velocity (and distance), target material and the angle of incidence". Obviously the bullet from the handgun is of a different composition than the shells used in the "Gatling gun" and the interaction between the bullet and his eye is different than that of the shells and his chest. Some bullets - like one fired from the handgun - are designed to deform on impact to reduce the likelihood of a ricochet.

Corrected entry: Jor-El's voice repeats something from the first film, that "by the time you get to Earth a thousand years will have passed", meaning that while his aging will be vastly slowed, the journey will take a thousand years. Yet Superman goes there and back in five years of real time using the same technology.

Correction:This isnt mistake because he did not say Earth years. For all we know a year on krypton could be a half a day to them.

Corrected entry: When Superman brings the plane to a halt on the stadium pitch, the nose cone only buckles a bit. Surely, under the strain of all that weight it would have collapsed?

Correction:It's an established, if infrequently acknowledged, part of Superman's powers in the comic that he's often capable of lifting and otherwise manipulating objects that should crumble or otherwise collapse under their own weight without this happening. It's often considered to be a form of touch-based telekinesis that acts to enhance the structural integrity of the object in question.

Corrected entry: During the "brakes out" scene, Kitty tries to stop the car by turning the key, but it is broken and gets stuck in the ignition, so the engine can't be turned off. You can hear it going in the rest of the shots. But when Superman lifts the car, suddenly the engine is dead.

Correction:Superman stops the car before he picks it up. Forcing a stop that quickly would cause the engine to seize.

Corrected entry: In the scene where Superman saves the plane from crushing, we can see that both of the plane wings were torn away in the air, but when they land they miracously disappear. No debris of any kind follows.

Correction:Superman guided the plane to a safe location. The wings, and other bits, would have fallen more or less straight down. Of course there's no debris nearby.

Corrected entry: Superman's strength and other superpowers seem to oscillate a lot between scenes in the movie, and for no good reason. Towards the end of "Superman Returns", he is shown lifting an entire landmass out of the ocean, and pushing it into outer space, all while being exposed to Kryptonite. He is also capable of showing up anywhere in the world nearly instantly, as a reporter comments. Yet in one of the first action scenes, he struggles trying to catch up with a plummeting airplane, and has a hard time slowing it down, managing it just before the plane hits the ground. This should be a trivial task for someone of his abilities, yet no in-movie explanation is given for such poor performance. Of course, the real reason is obvious - the plot requires that Superman saves the day just in the nick of time, to create cinematic tension and resolution.

Correction:He is able to lift the kryptonite island because he just got supercharged by the sun. There's the "in-movie explanation" for that. As for the airplane: He was simply going only as fast as necessary to catch up with it. Then, while slowing it down, he was being mindful of the people on board. As mere mortals, they are subject to the laws of physics. Specifically: inertia. If Superman had stopped the plane too quickly, those people would have suffered the same fate as if he'd let it crash into the earth. There is an old Chinese proverb which Superman adheres to (as do most superheros): "Never use a cannon to kill a mosquito." In other words, Superman only uses as much of his power as he absolutely must to get the job done.

Corrected entry: When Superman is first flying toward the Genesis shuttle, a controller says an unidentified bogie (Superman) is approaching from the North, but the computer screens (one of which even shows a compass) indicate that Superman is apparently coming in from approximately the South East.

Correction:It is traditional but by no means compulsory to have north uppermost on a map or radar screen, and in orbit where 'up' and 'down' are meaningless concepts anyway the radar screen could be oriented any which way.

Corrected entry: In the scene where Superman is lifting the newly crated island to space, he stops pushing it, and the island continues into space. Then suddenly, as he looses weight and mass (because the island is gone), Superman falls down towards earth. If he does, so should the island. Alternatively, if the island continues into space, so should Superman.

Correction:Superman didn't simply stop pushing, he gave it a final heave that cleared it of earth's gravitational pull. Superman, however, was not clear of it, and having passed out he was no longer able to maintain flight.

Corrected entry: After Superman exhausts himself from lifting the kryptonite-encrusted island his cape can be seen waving. However, there is no air in space so it would not be able to move the way it does.

Correction:This is not an error. After he collapses, his cape is waving very slightly as he re-enters the atmosphere. As he continues to fall, the air pressure increases and the cape waves more violently. There is nothing factually wrong with that scene.

Corrected entry: In the scene where Superman lifts up the sunken yacht in order to save Lois and her family it shows when he lets go that he was holding that entire half of the ship completely out of the water with one hand. This is impossible, assuming that he was able to lift that much that spot on the ship could not hold that much weight without ripping away from the rest of the ship.

Correction:In the comics, Superman has frequently been seen to lift something that should really crumble or break under the strain without it doing so, entire buildings, for example, to the extent that it is an acknowledged part of his powers (described as a unconscious tactile telekinesis holding the object together while he's in contact with it) that this occurs.

Corrected entry: As the plane falls to Earth toward the start of the movie, there is no sign of re-entry heat being built up on the plane do to air resistance and air compression beneath the plane.

Correction:A plane would not build up enough speed or resistance to show signs of heat. A plane staying within the atmosphere would reach terminal velocity long before it was going fast enough to heat up from friction. The aluminum and titanium of the fuselage can withstand very high temperatures, with melting point not until the thousands of degrees fahrenheit.

Corrected entry: In the scene when Lois and Jason pull up in front of Lex Luthor's house, we are inside Lois's car, and Lois's window is up because you can see the reflection. However, when they show a shot of Lois from the outside of the car, you can see that Lois's window is down.

Correction:No when Lois pulls up to the house we are outside looking in through the passenger side window (hence the reflection of the glass). When she gets out of the car we see the driver's side and that window is down.

Correction:How is the suit impervious to bullets? I'm sure that the suit and cape have 'special' abilities, one of which could be tucking it into his pants. Another one easily could be that it's extremely light and easily folded so as to avoid dection under a suit.

Corrected entry: An electromagnetic pulse (EMP), such as those caused by the crystal reactions, affects unshielded electronic equipment because it induces a voltage surge in their components, effectively 'frying' them. All affected devices are damaged permanently and would never work again, not even after a few minutes, as they portrayed to do so here.

Correction:Who said it was a pulse with the exact same properties as a nuclear EMP? For all we know, the wave simply saps out electricity.

Corrected entry: In the plane sequence the whole weightlessness is wrong. When the plane is high in the atmosphere the people inside it will still be under the effect of gravity (when the film shows no gravity) and then as it falls you would get effective weightlessness as everything falls at the same speed (yet the film has the gravity switched back on).

Correction:Whoever this twine guy is obviously doens't know his physics well enough. Should go read up something before putting something up here.http://en.wikipedia.org/wiki/Zero_Gravity_CorporationORhttp://en.wikipedia.org/wiki/Vomit_CometZero gravity can be experienced in a plane which is on a parabolic curve, and that's exactly what happens to the plane. And you gotta remember that the plane had gone up quite high with the shutttle on its back.

Corrected entry: Lex states that the crystals just need water to grow meaning that the new land must be somehow made from water molecules. In that case the land is effectively solidified water, lifted out of the ocean, meaning the worldwide water levels would drop, not rise. None of the flooding could ever happen.

Correction:Just because the crystals grow when placed in water, doesn't mean the resulting structure is made from water. When you water a seed, the resulting plant is not made from solidified water. The crystal probably expands in size exponentially when it hits water.

Corrected entry: In the scene where Superman is taking the Daily Planet globe down to the ground, there is a shot of his face. In the background you can see the Daily Planet tower with the globe on top.

Correction:That is part of the building just above the front doors, not the actual globe itself.

Corrected entry: In the scene when Superman pushes the Krypton continent into space his cape still has drops of water. Water freezes at high altitudes and in space.

Correction:It was established in the first Superman movie, and mentioned again in Superman Returns, that Superman's body is quite warm, which is how he can carry Lois above the clouds without her freezing. The water is being warmed by his body.

Corrected entry: Merely being in the presence of Kryptonite causes Superman a great deal of pain, yet he manages to walk atop an entire island infused with it without even noticing.

Correction:Remember, he is not walking on an "island of kryptonite" but an island with kryptonite pockets in it. It was also the crystal's version of kryptonite, and since it was not as potent as true kryptonite, it merely sapped his power, rather than causing him pain.

Corrected entry: Near the end of Superman when he reaches the new island he confronts Lex and suddenly becomes weak because there is Kryptonite near him. This makes him so weak that Lex and his 2 goons can beat him up and gives Lex the opportunity to stab Superman with a sharp piece of Kryptonite, Superman is then pushed into the water but manages to lift the island up (although being stabbed with Kryptonite) even though a large piece of Kryptonite is right in front of his face. Superman lifts the island into space before falling.

Correction:After Lois removes the kryptonite from his wound, Superman flies up close to the Sun, healing himself and "supercharging" himself to be able to move the island. Clearly he over exerts himself, as immediately afterward he falls to Earth.

Corrected entry: Listen closely to one of the newsreaders reporting on the new appearances of Superman on the TV in the Daily Planet offices, she mentions a few cities where he has been seen, including Gotham, home to another famous superhero-Batman.

Correction:There's nothing remotely surprising or noteworthy about a movie based on a DC comic making a blatant reference to the setting of another DC comic. There are probably DC superheroes in every one of the cities mentioned in that news report.

Corrected entry: When Lex reads the 'Superman is back' Daily Planet, it is dated something like September 16, 2006. Later, we see Superman on a store CCTV camera which is dated July 25. Then, on the 'Superman is Dead' / 'Superman Lives' Daily Planet covers the date reads something like September 27 2006. The date constantly changes.

Correction:It is possible that the date for the security camera was set wrong. Some stores only install the hardware but don't set the date and time correct. Human factor.

Corrected entry: During the airliner crash sequence, there are two cuts to the cockpit after both wings (and engines) have been torn off. In one, you can hear the flight deck computer saying "Overspeed. Overspeed". Later, after the plane is on the ground, you can hear "Fly up. Fly up." Both are valid warnings at the time, but without engines there is no power for these systems, and exterior shots don't show a ram air turbine deployed for backup power.

Correction:The computers and other electrical equipment on modern airliners are run on batteries that are recharged from the main engines during flight, like car batteries. The engines themselves do not power these systems directly. The computers therefore would still have power for the duration of the flight in the movie.

Corrected entry: During the out-of-control airplane scene, Lois (and other objects) are violently thrown around inside the plane. There are no bumps, bruises or scratches on any of the passengers or their clothing, and every hair is in place on Lois once the event is over.

Correction:Bumps, and especially bruises are not immediately visible in an accident. Also, the lady in front of her had her glasses askew and her hair very much out of place.

Corrected entry: Throughout the film, Superman's suit & cape are as impervious to damage as the man himself, even withstanding a full-on volley from a minigun. Yet when he is taken to hospital, the medics are able to rip open the chest area as if it was normal material. It can't be because his powers are waning, as they can't puncture his skin with a needle.

Correction:The medics didn't tear off the shirt: they simply removed it. It's shown to be in one piece, along with the rest of Superman's uniform when Lois and Jason come to visit him in the hospital.

Corrected entry: During the flashback, when Clark is learning how to fly he appears to be between 11 and 13 years old. In these scenes he is wearing glasses. In Superman I it is established that Clark did not wear glasses until he was a grown man. He is seen without glasses in Superman I as a high school-age teenager. He adopted the glasses as part of his "disguise" when he went to Metropolis.

Correction:Actually, Clark in this shot has been established as FIFTEEN by Singer and co, several years younger than the teenager we saw in Superman I. The implication established in this scene is that Clark DID need those glasses until his powers fully kicked in (with flight). This doesn't contradict the adult Clark later utilizing the glasses again as part of his disguise. It must also be noted that Superman Returns exists in a *vague continuity* with Superman I and II: not every single detail exists as we remember it. On the shelf with pictures of the Kents, we see a photo of a bespectacled Clark in graduation clothing. Clark may have worn glasses all his teenage life, up until adulthood. Perhaps the manifestation of his Kryptonian invulnerability/ abilities were sporadic until then, and he genuinely needed them.

Corrected entry: When Superman is hovering above the earth in space it zooms in on his ear, showing that he is listening to the whole world. The only problem is that you cannot hear in space. Sounds do not travel in a vacuum such as space, super-hearing or not.

Correction:It is likely that Superman is in the uppermost layer of the atmosphere - the exosphere, where sound can still travel.

Corrected entry: When Superman saves Lois and her family from the sinking ship you can see Superman's "S" through the window, but when we get an outside shot he is facing away from the window so there is no way we could have seen the "S" in the first place.

Correction:At no point is Superman facing the door porthole, nor do we see an interior shot from the inside seeing his chest. When the ship is underwater, what you see at the porthole are the soles of Supermans boots as he stomps on the door to lift up the ship half. Still holding onto the ship with one hand, he rips the door off/open with the other hand. The angle we see this happen is from the exterior of the ship.

Corrected entry: When the series of tremors causes the globe on top of The Daily Planet Headquarters to topple and fall, Superman catches it and places it on a car. When he flies away that night, at the end of the movie, and the camera spans Metropolis behind him, it sits in its original position on top of the Headquarters.

Correction:It could have been replaced or put back up and fixed in that amount of time.

Corrected entry: Jason must not have any super powers at all because Jason is the son of Clark Kent. Not Superman. As we all know in Superman II, Superman gave all his super powers up before he went to bed with Lois. He was just Clark Kent.

Correction:Except we don't know how his powers were removed - considering they're a by-product of our yellow sun (and that they were restored later) they can't just have been taken away from him. Most likely they were somehow suppressed, meaning that they were still present within him, just unusable, and that would mean they could still be passed on to a child.

Corrected entry: Lois's mind was erased at the end of Superman II by a "Super" kiss, but given that, how did she remember that she and Superman slept together?

Correction:We don't know exactly what she forgot. If Clark simply erased everything from the point where she learned his secret, she'd have a large gap that she would definitely want filled. He may have only made her blank out those specific parts that deal with Clark being Superman. Then she'd still have memories of almost all of the last few days and she'd be fine.

Corrected entry: Superman/Clark returns in a spaceship. Where did he get the spaceship from? The one he came in was destroyed and, even if it wasn't, it would be too small for him. What he returned in looked like a larger version of what he originally came in.

Correction:The crystals created the spaceship for him. They seem to create every artifact he uses. They created his first super-suit. In Superman 1, Jor-El says they contain the known knowledge of the 23 galaxies.

Corrected entry: Lex allegedly got off because Superman wasn't around to testify when an appellate court called him as a witness. Appellate courts do not call witness, they work from the transcript of testimony from trial courts. Only trial courts call witness.

Correction:This can very easily be a character mistake. We never see a file that says "Luthor got off on the Appalete courts" or anything like that. It's all word of mouth.

Corrected entry: In the scene where Lois and Jason are discussing Superman's physical characteristics, Lois states that Superman weighs 125 pounds. It should be 225, or at the very least the 215 pounds that Lois estimates as Clark's weight.

Correction:No, she actually says "220, 225." She rattles it off fairly quickly as she's describing him to Richard.

Corrected entry: When Superman is flying the new continent up and away from Earth, we see some Kryptonite right next to his fingers (actually, it's everywhere). It's already been established that Superman being near the Kryptonite on this continent will remove his powers, so he should not be able to fly, or be able to use his super strength.

Correction:Before Superman lifts the continent up you see him fly up really close to the sun, thereby not only restoring his powers but overstrengthening them so he could do that.

Corrected entry: A powered shuttle destined to leave the atmosphere could not be launched from the top of a flying jetliner for the simple fact that it would never be able to achieve escape velocity while flying. The speeds necessary to achieve sub-orbital injection require a near-100% vertical climb at speeds of well over 9,000 mph. If a shuttle flying at anywhere even near that speed tried to increase its rate of climb from horizontal to vertical, the aerodynamic forces encountered would destroy the airframe of the shuttle. Also, the shuttle's engines use a hypergolic chemical fuel reaction and the resulting thrust is so great that the the jetliner would have been instantly destroyed from the acceleration forces when it was still attached the the shuttle.

Correction:It is possible to make a shuttle leave the athmosphere on the back of an airplane. Never heard of the Spaceship One? Also, the thrust of an engine is not really related to the fuel used. There exist engines using hypergolic fuel with a thrust as low as a few kilograms. Anyway, if I remember well, the fuel used in the movie is kerosene or something similar, wich is not hypergolic. It's true that the scene is a bit exaggerated but not impossible.

When Lois pulls up to the house where the blackout was traced to, she hears some music coming from the boat down at the dock. As the camera pans upwards over the car, as she steps out, the whole camera and a crew member are reflected in the side of the car.
